Phison has a big advantage in terms of raw speed. The company produces E16 SSD controllers that third-party SSD vendors use to build the only SSDs on the market that support the PCIe 4.0 interface, giving them access to potentially twice the sequential throughput of any other model currently on the market. The E16's strength in sequential work is important: The faster interface pumps high-quality textures into the processor nearly twice as fast as PCIe 3.0 SSDs (up to 5GB/s), thus enabling richer scenes and smoother gameplay. Phison already has its next-gen E18 SSD controller in the works, too, that will push the bar up to 7GB/s.

recently visited Phison at CES, and the company also had new PCIe 4.0 SSD prototypes that cram an astounding 8TB onto a single M.2 SSD with the E12S controller, so the company is working to make both faster and more capacious SSDs that could all land in the same time frame as Microsoft's Xbox Series X.
